|First, is there a best option for security? Not data encryption but keeping people from accessing the meetings. |
We use Tandberg equipment where I work. I'm not sure if that's available in the US or not (should be) but their equipment offers it's own security built into the devices. The most basic being, you have to dial into a specific number to connect to it. You can't just "sneak" in when nobody's looknig because that's not how the equipment works. One unit calls the other in a one-on-one type situation and in a bigger meeting, one party hosts and the rest connect to it.
Also, we use VLAN's extensively where I work and our videoconferencing is it's own VLAN with it's own subnet. Firewall rules also preclude anybody not in that subnet/VLAN from accessing it ruling out any kind of man-in-the-middle attack.
The supplier(s) should be able to go through security questions with you and if their equipment doesn't offer any security, I'd thank them for their time and move on.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
